Trucks vary greatly in their size and power -- ranging from small ultra-light trucks to enormous heavy trucks. Trucks also vary greatly in their configurations -- ranging from very basic flatbeds or box trucks to highly specialized cargo carriers. Trucks may also be configured to mount specialized equipment, such as in the case of fire trucks, concrete mixers, and suction excavators.
